These system clocks are used to + * generate the CPU and bus rates and the individual peripheral clocks in + * the system. When Linux is started by the boot loader, the system + * clocks are already running. Stopping a system clock during normal + * Linux operation should never be attempted, as peripherals that require + * those clocks will quit working (ie, DRAM). + * + * The LPC32xx high level clock tree looks as follows. Clocks marked with + * an asterisk are always on and cannot be disabled. Clocks marked with + * an ampersand can only be disabled in CPU suspend mode. Clocks marked + * with a caret are always on if it is the selected clock for the SYSCLK + * source. The clock that isn't used for SYSCLK can be enabled and + * disabled normally. + * 32KHz oscillator* + * / | \ + * RTC* PLL397^ TOUCH + * / + * Main oscillator^ / + * | \ / + * | SYSCLK& + * | \ + * | \ + * USB_PLL HCLK_PLL& + * | | | + * USB host/device PCLK& | + * | | + * Peripherals + * + * The CPU and chip bus rates are derived from the HCLK PLL, which can + * generate various clock rates up to 266MHz and beyond. The internal bus + * rates (PCLK and HCLK) are generated from dividers based on the HCLK + * PLL rate. HCLK can be a ratio of 1:1, 1:2, or 1:4 or HCLK PLL rate, + * while PCLK can be 1:1 to 1:32 of HCLK PLL rate. Most peripherals high + * level clocks are based on either HCLK or PCLK, but have their own + * dividers as part of the IP itself. Because of this, the system clock + * rates should not be changed. + * + * The HCLK PLL is clocked from SYSCLK, which can be derived from the + * main oscillator or PLL397. PLL397 generates a rate that is 397 times + * the 32KHz oscillator rate. The main oscillator runs at the selected + * oscillator/crystal rate on the mosc_in pin of the LPC32xx. This rate + * is normally 13MHz, but depends on the selection of external crystals + * or oscillators. If USB operation is required, the main oscillator must + * be used in the system. + * + * Switching SYSCLK between sources during normal Linux operation is not + * supported. SYSCLK is preset in the bootloader. Because of the + * complexities of clock management during clock frequency changes, + * there are some limitations to the clock driver explained below: + * - The PLL397 and main oscillator can be enabled and disabled by the + * clk_enable() and clk_disable() functions unless SYSCLK is based + * on that clock. This allows the other oscillator that isn't driving + * the HCLK PLL to be used as another system clock that can be routed + * to an external pin. + * - The muxed SYSCLK input and HCLK_PLL rate cannot be changed with + * this driver. + * - HCLK and PCLK rates cannot be changed as part of this driver. + * - Most peripherals have their own dividers are part of the peripheral + * block. Changing SYSCLK, HCLK PLL, HCLK, or PCLK sources or rates + * will also impact the individual peripheral rates. + */ + +#include <linux/kernel.h> +#include <linux/list.h> +#include <linux/errno.h> +#include <linux/device.h> +#include <linux/err.h> +#include <linux/clk.h> +#include <linux/amba/bus.h> +#include <linux/amba/clcd.h> + +#include <mach/hardware.h> +#include <asm/clkdev.h> +#include <mach/clkdev.h> +#include <mach/platform.h> +#include "clock.h" +#include "common.h" + +static struct clk clk_armpll;
